AppIication filed March 5, 1904. Serial No. 196,766.

'1 b all whom it may concern Be it known that I, AR'ri-Inn J. ADAMS, a citizen of the United States, residing at Chicago, in the, county of Cook and State of Illinois, have invented certain new and useful Improvements in Peramb'ulators or (io-(Jarts, of which the following is a full, clear, and exact specification.

My invention relates to perambulators or go-carts, and has for its primary object to provide a folding perambulator or go-cart which shall be of neat, inexpensive and durable construction and capable of folding into a compact form.

lVith these ends in view my invention consists in certain features of novelty in the construction, combination and arrangement of parts by which the said object and certain other objects hereinafter appearingare attained, all as fully described with reference to the accmnpanying drawings and more particularly pointed out in the claims.

In the said drawings :-Figure 1 is a side elevation of my im roved perambulator, the seat being omitted lint indicated by a dotted line. Fig. 2 is a plan view thereof. Fig. 2 is a detail. plan of one of the forks. Fig. 3 is an enlarged cross section taken on the line 3-3, Fig. 1. Fig. 41 is an enlarged detail plan view of a locking mechanism hereinafter described. Fig. 5 is a detail perspective view showing one of the wheel forks or supports partly broken away,and Fig. (5 is a detail transverse section takenon the line o e, Fi 4-.

The runninggear frame is constituted by two side bars, 1, 2, which are preferably composed of wood, and a cross bar 3, which may be composed of an iron rod lo'olted through the side bars 1, 2, and also serving as the pivot or hinge for two side bars, 4, 5, of a hinged inclined seat frame, which is constituted by these side bars 4, 5, and a cross bar or rod (3 which is bolted through the upper or free ends of the bars El, 5, and which may serve as a means of supporting the upper end of the seat fabric, not necessary to illustrate, but indicated at 7 by dotted lines in Fig. 1, while the lower end of such fabric may be secured to the cross bar 3. The rear ends of the side bars 1, 2, are connected by hinges S, 9, to a folding handle, which is 'ireferably of U shaped form and constituted by two side bars 10, 11, and a cross bar 12, connecting their upper or free ends together. The lower end of this handle frame and the rear end. of the running gear frame are tied together and prevented from s n-carding by a cross rod 13 which extends through and constitutes the pivots of the hinges 8, 9. The lower leaf of each of the hinges is bent upwardly above the lower ends of the side bars 10, 11, as shown in Figs. 1 and 5, so as to support the pivot point on bar 13 at a sufficient elevation above these lower leaves to permit the handle 10, 11, 12 to fold down upon the running gear frame in a position substantially parallel therewith, the running gear frame and the U-shaped handle both being wider than the seat support 4, 5, 6, so that when the latter is folded down into a horizontal position it will liebetween the side bars 1, 2, and will be embraced by the handle 10, 11, 12, which is both wider and longer than the seat support.

The seat support is held in its inclined supporting position by two uprights or braces 14:, 15, whose upper ends are pivoted at 16 to the side bars 1, 5, while their lower ends are pivoted respectively to two links l7, 18, which latter are also pivoted to the side bars 10, 11 of the handle, and thereby serve to move the braces 14;, 15 forward and back as the handle is raised and lowered, thus autonnitimlly causing the seat supporting frame to rise or descend according to the direction in which the handle is moved. The lower ends of the seat support braces 14, 15, are secured together in any suitable way, such as a cross bar 19 having its ends extendingacross the two side bars 1. 2, and supported thereon with capability of sliding back and forth with the braces 14;, 15 as the handle is raised and lowered. This cross bar 19 serves as a means of carryinc and operating a lock for holding the braces 14, '15 in their upright or operative position. and this lock may consist of two longitudinally movable bolts or rods 20. 21, both pivoted to an operating lever 22, which is pivotally supported at 23 on the lower side of the bar 19, and the outer edges of these bolts 20, 21, pass through off-sets or angular bends 24, 25, formed in the bar 19 near its ends, and where they emerge from these off-sets they project into sockets 26, 27, formed in the side bars 1., 2, and thus lock the cross bar 19 against movement with the braces 14, This locking is effected automatically as the cross bar 19 moves rearwa'rdly during the movement of the handle 10, 11, 12, by two springs or other suitable cushions, 28, 29, one of which is sleeved on each of the bars or bolts 20, 21, between one side of the off-set and a pin or lug 30 passing through the bolt, so that when the bolts arrive at the sockets 26, 27, they will shoot into them.

Each of the four wheels, 31, 32, 33, 34, is journaled in a fork or wheel support, and each of these forks or wheel supports is hinged or pivotally connected to one of the side bars 1, 2, by similar means, a description of one of which will suffice for all. Thi means consists of a hinge having two leaves, 35, 36, pivoted or hinged together by a pin tle 37 at the inner corner of the side bar. The upper leaf 36 is secured by any appropriate means to the inner face of the side bar, while the lower leaf has an angular bend at 38 so as to make it fit under the side bar and thence extend down the side of the fork, which will be presently described, and to which fork it is secured by rivets 39, or other suitable means, so that when the cross bar 19 is pushed forward the wheel and its fork may be folded upwardly and inwardly on the centerB'T. Each of the front forks or whecl'supports is connected rigidly to one of the other forks or wheel supports by a longitudinal bar L0, pivoted or otherwise se cured at each end to the inner face of the hinge leaf so that when one of the rear wheel forks or supports is turned on its pivotal point 37 the front one will also be turned. Each of the rear wheel forks or supports is composed of an inverted U- shaped fork or flat bar bent into the form of an inverted U, 11, with its lower ends or branches pierced by an axle or pintle 42 upon which the hub 43 of the wheel is journaled. This pintle is held in place at one end by a cotter l i while the other end is provided with an L-shaped pin 45, one branch of which extends downwardly through the pintle while the horizontal branch passes through the inner branch of the fork L1, and thus holds the pintle from rotating .in the fork. The inner branch of the fork is secured to the outer face of the leaf 35 of the hinge, and such inner branch also extends above the bar 40 and rests flat against the outer side of the side bar 1 or 2 of the running gear frame and the upper end of the fork where it turns over the wardly by raising the handle from its folded position and thereby causing the lock or catch &7 to engage in the hook or notch 46, and thus lock the wheel fork from turning on its pivot 37, this locking being effected automatically with the locking of the cross bar 19 by the bolts 20, 21. It is understood, of course, that each of the rear forks is of the described construction and both ends of thecross bar 19 are provided with one of the catches or locks 47 for the purpose stated.

The front forks or wheel supports, which are shown at 458, are similar in construction to the rearforks 41 excepting that they are not provided with the notches or books 46, the same being unnecessary since the locking of the rear forks holds the front forks in position through the intermediary of the bars 40.
